Picture this: you start your system, but your SSD refuses to boot, and suddenly everything stops—your operating system, your work, and you can’t even access your important work files.
SSDs aren’t like hard drives; they don’t rely on mechanical parts, but they can still fail due to firmware, controller, or NAND flash problems. If any of these layers malfunction, or when your file system or bootloader data gets corrupted, your system might throw errors like “No bootable device found” or “SSD not booting,” or might even freeze completely at startup.
But don’t worry, because in this guide, we’re going to cover the most common SSD boot issues, their exact technical causes, and how you can fix them for good. We’ll also tell you when it’s best to stop DIY troubleshooting and let the data recovery professionals at Stellar’s ISO-certified labs handle it for you.
Common Boot Problems and Why SSDs Fail to Boot
Your SSD not booting problems can range from simple detection errors to complete system shutdowns. Now there are a few different fault layers: this could be related to the hardware, file system, firmware, or controller.
Here are the most frequent boot-related problems you will face with your SSD.
⚙️ Your SSD Is Not Detected by BIOS or UEFI
If your system can’t detect the SSD (“SSD not detected in BIOS” error), it’s probably because of hardware or firmware faults. This could be due to loose or oxidized connectors, a faulty power rail, or incorrect BIOS modes (for example, you switched from AHCI to RAID).
This happens because your SSD relies on a controller chip to announce itself to the motherboard (via SATA or NVMe protocols). Now, if that same controller’s firmware crashes during this handshake, your SSD effectively becomes invisible to the system.
💻 No Bootable Device or Operating System Is Found
This error occurs when your bootloader, partition table, or system files are missing or corrupted, which can happen due to improper shutdowns, malware infections, or a failed OS update. Your system’s BIOS will then fail to locate the boot sector and halt the process of booting up.
🌀 Your System Hangs or Freezes During Boot
If your computer stalls or loops at the startup screen, it could be because it’s reading data from bad blocks or corrupted file system areas. This is due to degraded NAND cells, which leads to inconsistent reads (can be caused by heat or unstable voltage).
⚠️ Blue Screen or Boot Loop
If you see frequent BSODs (Blue Screens of Death) or automatic restarts during boot, you’re dealing with driver conflicts, failing SSD controllers, or damaged BCD (Boot Configuration Data). So why does this happen? Well, in some cases, the OS misinterprets hardware faults for software errors, so it repeatedly tries to recover and reboot, leading to these SSD boot loop errors.
🕒 Your Boot Times Are Extremely Long or Inconsistent
Slow boot times are caused mostly by worn-out NAND cells, degraded firmware, or some other overworked internal process (like garbage collection). As your SSD becomes older, its internal spare block pool shrinks. The controller will then have to spend more time remapping failing sectors during startup, which makes your system appear sluggish or even frozen.
Now, if these symptoms last even after you try power resets, cable replacements, or BIOS tweaks, it could mean firmware or controller-level degradation is causing them. If this is the case, Stellar SSD Data Recovery experts can help diagnose and repair your SSD safely.
How to Fix SSD Not Booting Issues
Before you head to a professional data recovery service like Stellar, try these simple fixes (if they don’t work, don’t panic; keep reading to see what your other options are).
🔌 Check Your Power and Connections
Power off your system, disconnect your SSD, and then reconnect it firmly. You should also check the SATA or NVMe connector for any damage or dust, and make sure that your power cables are attached securely. Another thing you can do to rule out faulty connections is to try connecting your SSD to a different port or another computer and see if it gets detected.
⚙️ Check if Your SSD is Detected in BIOS or UEFI
Enter BIOS/UEFI (by pressing the F2/F10/F12/Del key while the system is booting) and check whether your SSD appears under the list of storage devices there. If it doesn’t, you’ll have to reset the BIOS to default settings or try toggling between AHCI, RAID, and NVMe modes depending on your SSD’s configuration (read the manufacturer guide to find this out, or you could look it up online). Also ensure that the SSD is listed as the first boot device in this list.
Note: The reason we listed this method is that sometimes your SSD can fail to initialize when the controller’s handshake with the SATA/NVMe host times out during POST (Power-On Self-Test). A simple BIOS reset can resolve this, so it’s worth trying.
🔍 Run Diagnostic and Health Tools
Check your SSD’s SMART status next. You can do this with manufacturer utilities or third-party tools like CrystalDiskInfo. If there are any reallocated sectors, pending sectors, or sudden drops in available spare blocks, you’re probably dealing with drive degradation.
The above fixes are relatively simple and won’t harm your SSD’s data. But if your data is already backed up and you aren’t worried about losing what’s on the drive, you can try the more advanced methods given below.
⚠️ Caution: The following methods are for more advanced users, and there are always chances of permanently losing data when trying repairs or reinstalls, so proceed with caution. Only use these if your data is backed up/unimportant and you know what you’re doing.
💿 Try and Rebuild the Bootloader or Reinstall the OS
If you think that the bootloader or system partition is beyond repair, reinstalling the OS on a clean partition might just restore functionality. Of course, make sure that you back up all your accessible data before you format the SSD, because reinstalling can overwrite even recoverable sectors.
🧰 Repair Your Boot Configuration and OS Files
You can boot your system using Windows installation media or a bootable recovery USB, and then use commands like bootrec /fixmbr, bootrec /fixboot, or sfc /scannow. These commands are system-level code lines that may rebuild your damaged boot records and help restore your corrupted system files.
🔄 Update Firmware or Drivers (Again, With Caution)
Outdated or corrupted SSD firmware and controller drivers can be fixed; simply head to the manufacturer’s website to check for updates (but never interrupt the update process or apply firmware meant for another model). Because a failed firmware flash might permanently lock your SSD’s controller and leave the drive inaccessible even to BIOS (something only professionals at data recovery labs can fix).
If your SSD remains undetected or continues looping after these steps, it’s likely because of a controller or firmware failure. You can’t reliably fix these through software and will need hardware-level recovery tools, which are only available at professional data recovery labs. Let’s see what to do in such scenarios.
How Stellar Can Help When DIY Fixes Don’t Work
If the SSD won’t boot due to hardware issues, continued troubleshooting can actually make things worse (especially if your drive’s controller, firmware, or NAND chips are involved).
Let’s understand something a bit more technical first—unlike traditional HDDs, your SSD uses more complex architecture where data is spread across multiple memory chips and managed by a controller with a unique firmware layer. When this layer fails, your system can no longer understand how or where data is stored. So, attempting repeated boots or firmware updates in this condition can trigger garbage collection or TRIM commands and permanently erase recoverable data.
That’s where Stellar’s in-lab SSD data recovery service comes to your rescue. Our SSD recovery experts in India can handle every type of SSD failure, from dead controllers and corrupted firmware to damaged NAND chips—and this is all done using proprietary specialized tools in ISO-certified labs.

Preventive Measures to Avoid Future Boot Problems
Here are a few smart tips to significantly reduce your risk of future SSD not booting issues and extend your drive’s life to the maximum.
⚡ Always Use a Stable Power Source
Unstable voltage or sudden power loss is what corrupts the SSD’s firmware in many cases. Invest in a solid UPS with desktops and ensure that your laptops have healthy batteries.
🔄 Keep Your Firmware and System Drivers Up-to-Date
Manufacturers keep releasing firmware updates to fix bugs and improve compatibility. Make sure you update the drivers as and when they release (although this happens automatically in most cases).
🧹 Maintain Sufficient Free Space
This is the easiest to implement. And the reason behind it is rather simple; your SSD needs free blocks to perform wear leveling and garbage collection efficiently. Just make sure you have at least 10–15% of space freed up.
🧰 Monitor Drive Health Regularly
This is another easy preventive measure—simply check your SSD’s SMART attributes every month or so using tools like CrystalDiskInfo (or the manufacturer’s utility).
☁️ Keep Regular Backups of Your Important Data
You should use cloud storage or an external drive to back up your data.
By using these preventive steps, you should be able to use your SSD reliably for years, but if you ever need to recover files from an unbootable SSD, Stellar data recovery specialists are just a call away. If a boot issue does arise, you need to know when to stop with DIY troubleshooting and turn to Stellar’s in-lab recovery service, as this can make all the difference between temporary downtime and permanent data loss!
Before we wrap up, here are a few more SSD-related articles that can help you understand and tackle similar issues effectively.
FAQs
1. Why is my SSD not booting even though it’s detected in BIOS?
This often happens due to a corrupted bootloader, damaged EFI partition, or missing operating system files. Repairing the boot configuration or reinstalling the OS usually fixes the issue, unless your SSD’s controller is already failing.
2. Can firmware updates fix SSD boot problems?
Sometimes. A firmware update might resolve minor bugs or compatibility issues that were causing boot loops or detection errors. However, if you apply the wrong update or interrupt the process, you can brick the drive, so proceed only after backing up your data!
3. My SSD shows “No bootable device found.” Is my data lost?
Not necessarily. More likely, the boot record or file system may be damaged while your data inside remains intact. Avoid reinstallation and if the drive becomes inaccessible.
4. Why does my SSD boot slowly all of a sudden?
Slow booting is caused by excessive bad blocks, write endurance limits being reached, or outdated firmware. It can also happen when your SSD’s wear-leveling or garbage collection routines are overloaded due to low free space.
5. Can Stellar recover data from an SSD that won’t boot or isn’t detected?
Yes. Stellar’s in-lab service can recover data from SSDs affected by firmware corruption, controller failure, power damage, or complete non-detection using advanced proprietary chip-off recovery and firmware reconstruction techniques.
